Retaining Wall?

[Matthew Sande]

The more terrain lines you enter, the more accurate your final view of the terrain will be.

For example, if I am drawing a terrain that is at a height of 0' for one side, then an abrupt change to 4' for the remaining terrain, I would start with two elevation lines, parallel to each other, just a couple inches apart. I can then leave one at a height of 0', the other at 4'. You will already see an abrupt change in a 3D view at this point, though the terrain will slope back to 0' the further from your 4' elevation line you get.

The more 4' elevation lines you draw, the more accurate the terrain will become.
